GPS点高程的确定方法

The Decision Methods of the Altitudes of GPS Points

以大水坡GPS点高程的拟合计算为例 ,通过对三种拟合计算所得成果的比较分析 ,可以认为 ,在平坦的小区域内 ,采用拟合计算的方法 ,GPS水准可以达到四等水准的精度。

In tis paper the imitation computation of DA SHUI PO GPS points os taken as an example,analysing and comparing the result of three kinds of imitation computation,it can be considered that in the plain ground and small area,by the method of imitation computation,the precision of GPS level is reached to that of the fourth class level.
